TSMJ/TMMJ/TPMJ Tapered & Lensed Fibers

Fiber Type Single Mode, Multi Mode Step & Graded Index; Input Core Diameter 100 to 600 µm; Output Core Diameter 50 to 200 µm; Numerical Aperture 0.12, 0.26; Wavelength 180 to 2400 nm; Sheathing PVC, Stainless Steel Fiberguide’s AFT/SFT series of optical tapers are used for mode mixing, lowering optical power density in high power applications, and converting numerical aperture (NA) in optical power delivery applications. Optical tapers can either be tower drawn, where the length is several meters, or they can be produced using bench-top equipment, making the length a few inches. In both cases, these optical tapers are continuous pieces of fiber, they are not spliced. Tapered optical fibers can be made either by fusing a short tapered section onto a longer fixed diameter fiber or by very carefully controlling the drawing process to produce a single continuous fiber with an integral tapered section. For its AFT/SFT series, Fiberguide uses the latter process since it results in superior fiber strength, alignment precision and optical power transmission. Tapered optical fibers cause optical mode mixing that tends to homogenize spatial power distribution. A larger input core diameter can prevent input damage and allow a smaller diameter pigtail for convenience in adapting to a wide range of optical applications. Tapered optical fibers can be used as a passive optical component to alter the input and / or output divergence (N.A.) with regard to an optical fiber, as a high power coupler for laser energy, as this will spread the energy over a larger area, or simply as a device to relax tolerances in an optical system. To ensure maximum efficiency of light transmission, the numerical aperture (N.A.) of the light entering the taper input should be 0.22 divided by the taper ratio. As an example, assume the input core diameter of the taper is 400 µm and the output core is 200 µm (2:1 taper ratio), then the N.A. of the light entering the taper will be 0.22/2 = 0.11. Additionally, the fibers can be equipped on demand with Fiberguide’s patented RARe Motheye anti-reflective technology that enhances fiber transmission performance and significantly increases the damage threshold for your application over a large wavelength range.

Fiber Type All Silica, Step Index MM, Hard Clad; Single Fiber; Wavelength 190 to 1250 nm; Sheathing Acrylate, Polyimide, Nylon, Tefzel, Gold, Aluminium; Termination 905 SMA, FC/PC, ST/PC, Cleaved Ends, Polished Ends, Round 2.5mm Ferrule, FD-80 High Power, 905 High Power, Custom Shaped fiber tip assemblies provide optimum control over beam delivery and/or increased efficiency of light collection. Fiberguide offers standard configurations like angles, ball, radiused, conical, chisel or diffuser tips, as well as custom designed shaped tip fibers assemblies for precise beam control. A shaped tip on the end of an optical fiber allows for a wide variety of different outputs and inputs; they are most commonly in the medical field as laser scalpels, to remove plaque buildup in arteries, to close varicose veins and to couple diodes into multi mode optical fibers. Shaped tips are also used to provide diffused outputs and as radial emitters, perpendicular to the face of the fiber. The shaped tips are bare or encapsulated in a glass tube, to prevent fluids and other materials from impacting the shape of the light output from the fiber. Fiberguide designs and manufactures shaped glass to manipulate the light inside fibers. Fiberguide offers shaped tips for a broad range of multi mode fibers, including step index MM fiber series like AFS/AFM/AFH/SFS/SFM/SFH all silica optical fibers, AFSH/SFSH hard polymer coat fibers, APC/SPC polymer clad fibers, APCH/SPCH hard clad fibers, AFR/SFR Uniclad™ high power fibers or Solarguide™ solarization resistant fibers, but also AGI/ASI anhydrous graded index fibers. For high temperature applications, some fiber types can be aluminium or gold coated on request.  Additionally, all fiber types can be equipped on demand with Fiberguide’s patented RARe Motheye anti-reflective technology that enhances fiber transmission performance and significantly increases the damage threshold for your application over a large wavelength range.
